Please don't. I think 5 years is the minimum a console should get. Wii U still has enough to push it through 2016, and could survive 2017 with games like Animal Crossing and Paper Mario. Please do not do this. This is what Sega did with the Saturn.

Xbox(2001) -> Xbox360(2005),

GBA (2001) -> DS (2004)

Things will work out fine, the sales just arnt there to support a longer gen with the Wii U.
